As shown in Fig.4, where the present results are compared with those from a previous study conducted at room temperature, the rate and extent of moisture uptake in composites is sensitive to temperature. Most composition in the room-temperature study were observed to plateau at 0.75-2% weight gain,while N1-220-50 showed a 7% weight gain without platrauing.Such trend was attributed to the degradation of thin walled particles to the extent that the moisture started accumulating in the cavity inside the particle. Accelerated degradation in the present study is likely due to a similar mechanism, which results in the observation that the composite not saturated within the test time frame. Such possibility will be further examined through microscopy
