This paper investigates the thermal degradation and water absorption behaviours of OPFB composites and OPFB hybrid composites at different OPFB size. The result shows that TGA test can be used to estimate the percentage of filler in the composites. Incorporation of OPFB in PP has decreased the degradation temperature of composites. Water absorption test was conducted on OPFB composites at different OPFB size, which showed that higher OPFB size tend to absorb more water due to its pores structure. Most OPFB/PP composites reach water saturation at about the same time which was on the 150th days with about 3.0% - 3.5% water uptake. The presence of nanoclay in OPFB/PP composite has increased the water uptake of about 9%.

Parameters for measuring the physical properties on this research are divided into three elements, including measurement of weight, water absorption, and density. This research was conducted from January to March 2018 to determine the physical properties of wood powder composites and bagasse. The manufacturing and testing process refers to the ASTM and JIS standards. Weight and density testing refer to the ASTM D 792 standard while the water absorption test refers to the JIS A5908 standard. The results showed that the density of wood powder was 0.4175 gr / cm3, and the bagasse was 0.3125 gr / cm3. Then, fiber absorption in units of volume to water and resin were 16.88% and 13.75% respectively. The results showed that the largest water absorption was found in composite wood powder 60% and bagasse 40%, which was 13.47%, and for the highest density values found in wood powder composites as much as 80% or 1,078.29 kg / m3

This research investigated the tensile and water absorption properties of kenaf fibre mat/polyester composites. Treatment using acetylation method has been introduced to improve the properties of product manufactured. The effects of acetylation treatment with three variations of time that were 1, 4 and 24 hours on the kenaf fibre mats were investigated. The MOE of the tensile of treated fibre mat/polyester composite for 1 hour was the highest with value 4589.61 MPa. The tensile strength of treated fibre mat/polyester composite for 4 hours was the highest with value 0.6213 MPa. For water absorption test, the results showed that fibre mat/polyester composite with treatment duration for 1 hour had the lowest water absorption that was 1.23% compared with treatment duration for 4 hours and 24 hours. For overall it can be concluded that the treatment duration of 1 hour was recommended for acetylation method when compared with 4 hours and 24 hours duration treatments. Using acetylation treatment on the kenaf fibre mat/polyester composites was showed improvement on composite and was recommended in short duration of treatment.

The objective of this research is to determine the physical quality of food media, consisting of small plate, large plate and small bowl. The method used of this research is testing the water absorption and resistance of the food media’s temperature. The process of making a food media using a stainless steel mold which is heated using a food thermometer with 100   and a load of 10 kg as a pressure, then it is printed for 5 minutes with 4 times taking the data for each food media. There are two testing of food media, the first test is water absorption with 29.5  for 125 miles into a small plate, 200 miles into a small bowl and 250 miles into a large plate for 60 minutes, the average value of the water absorption test for the Non-woven food media consists of three forms food medias have 0.00  as the same result, meanwhile woven media such as small plate has 65.00 , large plate has 44.83 and small bowl has 66.68 .  Second test is resistance of the food medias based on temperature parameters. The temperatures used were 40, 60, 80 for non-woven food media consists of three forms food media which had few change after drying, while for woven food media consists three forms of food media had the same results, that is seepage (leaking) in the food media.

This paper deals with the investigation carried out to study the Strength Properties of Papercrete Building Bricks and these results were compared with conventional bricks. The papercrete brick did not fully collapse even at ultimate load and it never failed catastrophically. Hence the outer faces got cracked and peeled out. From the observation of the compression test, it is inferred that the papercrete bricks are having less elastic and are less brittle. Water absorption test was carried out as per the guidelines given in ASTM C-642. After coated with an external coating agent, the percentage of water absorption of the papercrete bricks was nearly the same as the conventional bricks. Also young’s modulus and poisson’s ratio of coated papercrete bricks was determined.

Toughened epoxies reinforced by hybrid of kenaf/carbon fiber, untreated and treated, with the addition of liquid epoxidized natural rubber (LENR), were tested for their water absorption and thermal degradation. Water absorption testing was conducted based on ASTM D1037 to study the effects of kenaf fibre and carbon fibre on water uptake property. In the thermal analysis, the thermal degradation of the specimen was investigated towards heat. The test used a termogravimetric analysis machine, model Mettler Toledo-TGA, at temperature range of 50 OC to 350 OC with an increment of 10 OC/min where the results showed the decreasing of degradation temperature when the treated fiber was used. The results also showed that the percentage of water absorptions for composites with the addition of LENR were lower compared to those of composites without LENR.
